You might have come across the concept of photo stacking before, because it’s the basis of high dynamic range photography, commonly referred to as HDR. As we saw in LXF257, this technique is used in scenes with very light and very dark areas because normal photography isn’t capable of recording large differences in brightness in a single shot.
Before looking at the processing, we’ll provide some advice on taking the sequence of photos – something that applies to all types of photo stacking. A key requirement is that all the shots capture the same scene. If you don’t manage that it’s not necessarily a deal-breaker, but if the individual photos don’t match up then the processing will be more involved.
For good results, you’ll need to use a tripod so your camera or phone doesn’t move between each shot.
